How do I Autocomplete using JSON response
I am making a mock trading website and I need to populate an autocomplete dropbox with options, gotten from a JSON response. Here is some background, I am using Django for the backend and Materialize framework for the front end. And I am getting the JSON response from the IEX cloud API. I am using their search functionality. The problem: When a user enters the name of the company they don't always necessarily know the right symbol as well, so if I can make a drop-down box that makes it easier for them that would be awesome. The solution I envision: As the user types the name of the company it starts to give us autocomplete suggestions just like this: What I need: If you could give me a direction, a starting point, a resource I would be very happy. I have been roaming around the interwebs but I seem to find a solution, so if you can point me in the right direction that would be very much appriciated. -
Insert lat and lon in model fields after user fills in address
Is it possible to call an API (eg. Google Maps API) on submit (or even before submit?) and insert lat and lon values in the model's fields so they are saved to the DB my app is connected to? I want to re-use those values later in a view on the front-end outside the admin to plot them an a map. models.py: from django.db import models from django.db.models import Q class Address(models.Model): street = models.CharField(max_length=100) number = models.IntegerField(null=True) postal = models.IntegerField(null=True) city = models.CharField(max_length=100) country = models.CharField(max_length=100) is_primary = models.BooleanField(null=False) geo_lat = models.DecimalField(max_digits=22, decimal_places=16, blank=True, null=True) geo_lon = models.DecimalField(max_digits=22, decimal_places=16, blank=True, null=True) created_on = models.DateTimeField(auto_now_add=True) updated_on = models.DateTimeField(auto_now=True) customer = models.ForeignKey("Customer", on_delete=models.CASCADE, related_name="addresses") class Meta: verbose_name_plural = 'Addresses' constraints = [ models.UniqueConstraint( fields=['customer'], condition=Q(is_primary=True), name='unique_primary_per_customer' ) ] def save(self, *args, **kwargs): if self.is_primary: self.__class__._default_manager.filter(customer=self.customer, is_primary=True).update(is_primary=False) super().save(*args, **kwargs) def __str__(self): return f"{self.street} {self.number}, {self.postal} {self.city}, {self.country}" class Customer(models.Model): name = models.CharField(max_length=100) email = models.EmailField(unique=True) vat = models.CharField(max_length=100) created_on = models.DateTimeField(auto_now_add=True) updated_on = models.DateTimeField(auto_now=True) def __str__(self): return f"{self.name}" -

Implement f-string like magic to pimp Django's format_html()
I would like to pimp format_html() of Django. It already works quite nicely, but my IDE (PyCharm) thinks the variables are not used and paints them in light-gray color: AFAIK f-strings use some magic rewriting. Is there a way to implement this, so that the IDE knows that the variables get used? Related: Implement f-string like syntax, with Django SafeString support -

Django's Memcache VS Database Cache. Which is better?
I am trying to develop a site using django framework which might have a mid level traffic and I have hit a wall. I want to include sessions in my pages but to implement session I need to employ caches. There are two different types of cache based sessions as given here. My site will be on only for a certain time in a year during which I expect mid level traffic of say around 200 visitors per day. What kind of cache system should I use for this? I understand that database cache means that every time a user visits my site, the backend will have to search the database which means more processing power, but for my requirements I think this would not matter so much. Any help and advice appreciated -
Django Rest Framework Include ManyToMany attributes in slash with all features

Item id and order_variants id stored as null while creating an order in django rest framework
I created an order-create API where I am creating order by creating order items objects and billing details objects at the same time.

Django submitting multiple forms in one page
I have a store with the models: Items, Cart. I created a loop to display the Items in the html file but only if they are in stock (if quantity > 0). However, the user can only add 1 item at a time and the page has to refresh. I'm trying to do it so that the user can enter the quantity for each item and then have one submit button for them all, but I can't seem to figure it out. I tried modelformset and formset, but the examples are confusing. Django's documentation shows it in console mode and it doesn't match when I'm trying to do. Here are the models: #model: Items class Items(models.Model): STORAGE_TYPE = { ('Dry', 'Dry'), ('Frozen','Frozen'), ('Refrigerated','Refrigerated'), ('Other','Other'), } ITEM_TYPE = { ('Produce', 'Produce'), ('Grains', 'Grains'), ('Protein/Dairy', 'Protein/Dairy'), ('Extra Items', 'Extra Items'), } item_name = models.CharField(blank=False, null=False, max_length=255, unique=True) weight = models.FloatField(blank=False, null=False, default=0) quantity = models.IntegerField(blank=False, null=False, default=0) description = models.TextField(max_length=1279, blank=True, null=True) image = models.ImageField(upload_to='fp/', null=True, blank=True) price = models.IntegerField(default=1, blank=False, null=False) storage_type = models.CharField(max_length=255, null=True, choices=STORAGE_TYPE, default="Dry") item_category = models.CharField(max_length=255, null=True, choices=ITEM_TYPE, default="Produce") limit = models.IntegerField(default=999, blank=False) show = models.BooleanField(default=True, blank=False, null=False) date_created = models.DateTimeField(auto_now_add=True, null=True) modified_timestamp = models.DateTimeField(auto_now=True, null=True) #model: … -

Django: ModelFormSet.is_valid() throws django.core.exceptions.ValidationError: ManagementForm data is missing or has been tampered with
I know this error has been asked about before plenty of times on SO, but none of the other threads that I read seem to have the same situation as me, in that I am not trying to render the formset AT ALL. I simply want it for posted data validation purposes alone. Is this not a supported way of using ModelFormSets?

How to implement password change in Django Rest Framework without repeating code (DRY principle)
I have a Django app that already has a web interface for changing passwords. It uses django.contrib.auth functions and django.views.generic.UpdateView. Here is the code: class PasswordChangeView(LoginRequiredMixin, generic.UpdateView): form_class = PasswordChangeForm template_name = 'form.html' input_value = 'update password' def post(self, request, *args, **kwargs): form = PasswordChangeForm(request.user, request.POST) if form.is_valid(): user = form.save() update_session_auth_hash(request, user) # Important! try: request.user.auth_token.delete() # Important! except (AttributeError, ObjectDoesNotExist): pass messages.success(request, 'Your password was successfully updated!') return redirect('/') else: messages.error(request, 'Please correct the error below.') def get(self, request, **kwargs): form = PasswordChangeForm(request.user) return render(request, self.template_name, {'form': form, 'input_value': self.input_value}) The above code works fine in the web interface. Now I want to implement REST API for changing passwords. I know that I can create APIView/viewset and serializer to do that (like the answers for this question), but it will violate DRY principle. What is the best way to implement the REST API interface for that given that there is already a fully-functional web interface? -
